Emery is using a coordinate system to make a parallelogram-shaped machine part. Side AB¯¯¯¯¯¯ passes through the point (0, 8) and is perpendicular to the graph of y = 1/4x + 2. Side CD¯¯¯¯¯¯ is parallel to side AB¯¯¯¯¯¯ and passes through the point (–3, 6). Which is the equation in slope-intercept form of the line that includes side CD¯¯¯¯¯¯?
A. y = 1/4x + 6
B. y = –1/4x + 8
C. y = 4x – 8
D. y = –4x – 6
